What are the differences between the surrounding air and exhaled air?
The air you breathe out is little changed from the air you breathe in, except that the oxygen content is somewhat lower - your body extracts some (not all) of the oxygen. The exhaled air is the same except for slightly lowered oxygen content.
What are 4 products or characteristics of exhaled air?
Exhaled air is made up of78% nitrogen13.6% - 16% Oxygen4% - 5.3% Carbon Dioxide1% Argon and other gasesDifferences from inhaled air include that it has more CO2, less O2, and it generally has a higher temperature (depending on the temperature that day).
Is the air you breathe out warmer or cooler than the air you breathe in?
We can say that air we breathe out is warmer, because if we breathe out on a mirror we can see droplets of water which means air is hotter compared to normal room temperature air because the room air condenses. Exhaled air is warmer than inhaled air because its the same room temperature air which we have taken in.
Does air contain mold?
Air in itself does not contain mold. Though it will carry the mold particles which help spread it around.
How long will balloons float filled with exhaled air?
When a balloon is blown up by mouth, it will not float, but fall to the ground. This is because the air inside is the same density as the air outside. For a balloon to float up into the air, it must be inflated with a gas that is lighter than air - such as helium.
